I have an electrical problem I think, HELP!!!

I have a 99 Montana, I've been having problems for some time, It started out with the anti lock break lights on inside the dash, I could back the car out of the garage, shut the car off, restart the car and put it in gear and the light would stay off till the next day, sometimes sooner. And the blinkers would blink real fast when I stepped on the breaks, been doing that a few months, and now the anti lock break lights are out but the blinker lights are both on solid at least most of the time, the blinker lights on the outside are real dim and blink faster than normal. I also have no brake lights. The radio display light will also blink real fast too.The head lights have a lot of water in them , like lots of humidity, aren't they suppose to be sealed? Could they be shorting something out? I have the mechanics stumped. Got to get this fixed can you help me out.? Gramma in Nebraska

A lot of the electrical issues can be tied to the rear lights. There is a problem when water gets into the houdsing and shorts out the connections. If you look at where the bulbs sit in the housing (also called a "board") you can see burnt areas where damage has occurred. The boards can usually be purchased rather inexpensively through eBay.On the headlight issue, it sounds as though the seal around the lens may be failing, letting water into the capsule. Being 10 years old, the glue that holds the lens to the housing starts to come off and fail due to environmental extremes and the sun's UV rays.
